Brief description of the drawings
Fig. 1 is gravity flow SNCR denitration system structure chart of the present utility model.
Embodiment
The utility model protects a kind of gravity flow SNCR denitration system, as shown in figure 1, it is molten comprising the urea being sequentially connected
Tank 5, supply water pump module 6, intermediate storage tank 8 and some gun systems 11, the entrance point of urea dissolving tank 5 is solved to connect to provide
The solid urea device 1 and desalination water installations 2 of raw material.Key protection point of the present utility model is, horizontal residing for intermediate storage tank 8
Position is higher than gun system 11, to provide the potential energy of urea liquid flowing.
Above-mentioned supply water pump module 6 is that two-way water pump pipeline is in parallel, the using and the reserved, ensures the normal operation of denitrating system.
Air accumulator 9 in system of the present utility model also comprising distribute module 10 and offer compressed air, distribute module 10
It is arranged between intermediate storage tank 8 and gun system 11, distribute module 10 is by the urea liquid pipe of the outlet end of intermediate storage tank 8

Water pump module 6 is stopped.
The urea liquid of intermediate storage tank 8 enters distribute module 10 from outlet end, the compressed air of air accumulator 9 also by
Pipeline enters distribute module 10, by the change to NOx concentration level, automatically adjusts the stream of reactants of the port of export of distribute module 10
Amount.The port of export of distribute module 10 is connected by compressed air piping and urea liquid pipeline with each gun system 11, compressed air
Pipeline is that gun system 11 provides atomization required compressed air, and urea liquid pipeline is that gun system 11 provides reactant, spray
Gun system 11 is ejected into 10% urea liquid in the hot-blast stove of spray tower, position of the temperature at 900 ~ 1100 DEG C.
The hot-blast stove of ceramics factory's spray tower, denitration are successfully applied to using gravity flow SNCR denitration system of the present utility model
Efficiency surpasses 50%, stable and reliable operation.
